Be it known that l, lliiirrnn lll. (lessi/ino, a citizen of the UnitedStates, residinr,v at New Yor t, `in the coiinty ot lilew York and Stateoil. New York, have inventedfcertain new and use'lul Improvements inPost and Cover Clamps and Seals, of which the tollowing` is aspecification.

This invention relates to an improvi-id post and cover clamp and sealthat esjgiecially adapted for retaining' a storage battery ter-- minalpost in place in an openingin the cell cover and 'for sealing` the jointbetween such post and opening. llhe broad principles olf the inventionmay, however, be ein-- ployed in retaining and sealing; a similarrod-like member in an opening in a similar plate-like member.

In storage batteries ot the type employing` terminal posts projectingthrough openii s in the cell covers, it is necessary to secu ,ly retainthe terminal post in its opening` and also to provide means forsealing)1 all joints to prevent leakage and evaporation et the acidelectrolyte. Accordingly, the principal object of this `invention is toprovide a simple and ellicient means whereby a terminal post may besecurely held in place and sealed in an opening, in a cell cover.Another object of the invention is to provide tei minal post retainingand sealing1 means otthe above character which will. permit thedisconnection ot' the post and cover for the purpose oil repairing;v orreplacingn parts.,

i/Tarious methods'have heretotore `been eroployed for sealing a storagebattery terminal post in the opening in the cell cover, but in certain.instances the securing` and sealing' means are complicated and in otherinstances they do not provide a satisfactory seal or may notbedisassembled i"tor repairing; or replacing parts.

Generally speaking, l attain the above and other desirable objects olEmy invention by :forming the cooperative parts et the terininal post andcell. cover oit a tapei.I lit and provi dingI a ring, desirable aonepiece split ring, to clamp such post and cover in ing position and tointerlock erich p ts againstrelative separating movement am ally of thepost.

The above and other objects and the novel features ot this inventionwill be apparent l bat "l lll l Clt" 39530. Serial lilo. lhUlQ.

'from the following description talren in connection with the dr winpg,in which- Il, 2 and 8 are separate perspective views respectively, oit asplit ring, a portion ot cell cover plate and a storage battery terminalpost arranged l'or assemblingI `in connected and sealing relation, inaccordn anco with the present invention,

fl; is a 'oss-sectional view ol a portior. oi? a sto ge battery cellillustrating a cover and post clamp and seal embodying this invention,and

and. 6 are, respectively, a plan view and an` edpge view, partly insection on the line G- f oil Fir. 5,. illustrating; a split clamping`and scali j "ng employed in carifi/'ingr ont the present invention.

.l e'lierringr to the drawing, the usual or prererred type oit jar of astorage battery cell, adapted to contain the elements of the battery,such as the positive and negative plates nd separators and theelectrolyte, is provi( .fl with suitable cover C adapted to close theupper ond ol the ar to prevent the leakage and evaporation olfelectrolyte thorelrom and to enclnde foreign matter from the interior ofthe cell. Both the bat tory jar (not shown) and the cell cover C may bemade ,t suitable non-corrodiible comparatively ri;id, but elasticmaterial such as hard rubber, and the cover C provided with openings,snoh as the openingr l() through which the terminal posts ot the such asthe post l', project trom the inside oli the battery to the ontside toconnect the positive and negative vplates to tio external circnit oitthe battery. le herein illustrated, the portion of the cover C adjacentthe openinp; l() is thickened to pro vide suitable retaining,` andsealing surfaces 'tor engagement with the terminal post, but it will beunderstood. that the entire cover may be 'termed ot the thicknessdesired at the openinp1 l0. n

The tervr nal post P ,is ol .suitable lead alloy or other non-corrodiblemetal, and has the usual'plate strap ll, at its inner end. .llbove theplate strap- 1l the terminal post ll is provided. with an enlargement orcollar forming,A a shoulder i3 that abuts against the inner side oit thecover C adjacent the inner end olf the openinrilO, when. the partsclamped topjether.D

The terminal post P may be clamped in sealing relation with the cover Cand interlocked against relative separating movement lll by any suitablemeans. I have herein illustrated a simple and efficient mea-ns for sointerlocking said post and cover as to prevent their relative separatingmovement and at the same time maintaining such post and cover in sealedrelation with one another. In the arrangement illustrated the opening 10in the cover is desir-ably provided with a tapering socket 14 thatflares downwardly from a section 15 adjacent the upper end of theopening at the lower end of a downwardly inclined or'tapering seat 16,which latter is formed at the upper end of the opening 10. The taperingsocket portion 14 is adapted to receive a similarly tapering portion 17of the terminal post P and to effect a sealing engagement therewith.Above the tapering portion17, the terminal post P has a groove 18 thatfaces the tapering seat 16'in the cover, such groove having upper andlower walls 19 and 20 disposed above and below said seat 16 and arrangedin planes substantially perpendicular to the axis of the post to formabrupt shoulders, the wall 19 constituting a locking shoulder forinterlocking with the upper edge of a clamping ring R, to be described.The head portion 21 of the terminal post P above the shoulder 19 is of adiameter that will readily pass through the smallest part of the opening10 and is adapted to have the connector of the external circuit attachedthereto.

The securing or clamping ring R by means of which the terminal post P isinterlocked with the cover C against relative separating vmovementtherefrom and clamped in sealing relation thereto, may be of anysuitable form that will obtain the desired results and I have hereindisclosed a desirable construction in which the ring consists ofsuitable flexible or yieldable non-corrodible material such asantimony-lead alloy, the ring being formed in one piece and splittransversely as at S to provide ends which are separable so that it willreadily pass over the head portion 21 of the terminal post, such endsbeing closable together when the ring is in place. The ring is providedadjacent its lower outer edge with an inclined or camming face l2adapted to engage and cooperate with the seat 16 of the cover tocontract or force the ring inwardly into the groove 18 as it is forceddownwardly axially of the terminal post. When the ring has been pusheddown sufii'ciently far so that its upper edge passes below the shoulder19 of the groove, the cooperating tension in the cover and splitformation of the ring will cause the ring to spring into place into thegroove 1s with the inner wa11 ,Qf the. fing abutting against Ithe Vbtfonof the groove and ends at the split or gap S disposed close together orclosed. At the same time, the shoulder 13 is drawn into abuttingrelation to the lower side of the cover and the tapering portion 17 isdrawn into the socket 14 of the opening 10, thereby effectively sealingthe assemblage. Axial pressure on the ring.r R to secure it in place maybe applied by any suitable means. assemble the parts for any reason, thering R may be readily withdrawn from its interlocking relation and thepost withdrawn from the openingr 10. T he terminal post P and partscooperating therewith may be of rectangular or other section than thecircular section herein disclosed.

lVhilc I have shown and described the invention in detail, it is to beunderstood that various modifications may be made therein withoutdeparting from the spirit of the invention or sacrificing :inv of theadvantages thereof. and therefore I do not wish to be limited to theexact structure disclosed.

I claim:
